This chart lists the basic endings for the six prinicpal case forms of nouns and adjectives. Variations of these are the result of applying spelling rules, or several variants of a few specific endings. The endings that have variants are marked with an asterisk in the chart; click the * for details.
To spell zero (-#), use -ь for stem-final palatalized consonants (дІня — дІнь), -й for stem-final /y/ (задђние — задђний, истћрия — истћрий), and nothing at all after other stem-final consonants (кнќга — кнќг).
Blank spaces appear in the chart as a result of one or both of the following:
   (1) o-declension noun endings are listed only when they differ from the endings of the #-declension. This reflects the fact that there is very little difference between the two declensions: if you know one, you know the other, except for the Nominative/Accusative and the Genitive Plural.
   (2) Plural endings are listed only when they differ from those in the upper right-hand block, where adjective and #-declension noun endings are displayed. This reflects the fact that the 4 declensions of nouns do not differ in the Plural except for certain Nominative and Genitive endings, and also the fact that adjectives make no gender distinctions in the Plural.
